Hey bro, and welcome! I have been using this site for about 8 months and love it. It has been my greatest advantage.
I am a BIG classic rocker too. I love it and I love to play it. I have been "playing" guitar for about 15 years, but only 10 months wih real lessons.
As a few have said your greatest advantage to playing better is lots of practice. This site will get you there and you will get out of it what you put into it.
As for gear, I personally am NOT a fan of the line6 gear. I have heard so many people talking about how great they are. So I tried the spider jam, although it had some nice features, the tone just killed it for me. I love and am true to the classic rock tone that didnt have all that digital mumbo jumbo. If you want distortion, turn it up, or use a good overdrive pedal.
I also recently tried the pod2.0, returned it too. Same problem, the fine tone quality just wasnt there, I just couldnt enjoy playing if i didnt like what I was hearing.
Now for my advice, for what its worth. Musical instruments are expensive, plain and simple. You do get what you pay for. Now is what I would probably do, is just live with it for a while. Try it out, learn a little and see if you really want to play and do this before you make much more of an investment. Which is exactly what I did. A few things that you can do that may improve your experience is spend a few bucks on a set up, or learn how to do some of it yourself. Things like adjusting your truss rod, checking your intonation can make a big difference in sound and playability. In my experience those starter guitars will be at least playable if they are propperly adjusted. It is pretty common for those to be sold with the action (neck tension) and intonation out of wack. There are a lot of decent tutorials on the web for doing this, as well as the ask the tech section on this forum.
Now for the gear to think about when you are ready to take the plunge. First advice is drive to the local music shop and try every guitar in your price range, and maybe a few a little below and above that for compairison. The Fender Strat is a good choice for classic rock. The mexican made ones are fairly good and sell in the 3-600 range. I have one that I am fairly happy with, (I did tweak it a bit over time). I get a pretty good SRV/Hendrix/Clapton sound out of it. Take a look at the Epiphone axes too. They sell some pretty low end ones in the low hundred range which I have no experience with. But the ones that sell in the 3-600 range are pretty good. I had an Epi LP that I really liked (it was stollen). Now if you want to go more full tilt, look at the Gibsons. They start at the 700 range and go way up from there. The "Faded" ones sound/play pretty good. They just save on the cosmetics. I have a Gibson SG Diablo Custom that I love to bits. It is by far the best guitar I have EVER laid hands in 15 years of playing. I paid about 1800 for it though, but it was worth every penny. Plays like a dream and I can play any classic rock sound on it I want. I can even get pretty clean or real heavy sound too. As for amps. When you are ready for a good mid range classic rock amp, look at the Fender Blues JR, or the Marshall Haze. I plan to pobably get the Haze when I am ready for a bigger amp. For now I have a little Vox AC4tv. It is a nice little tube amp that has the pure classic tube sound. It is only rated at 5watts, but when I really crank it, it sounds louder (and much better) than the 75watt Line6 i just got rid of. I added a tube screamer pedal and I am classic rockin' my... butt off. Now if you'll excuse me, all this talk is making me want to play!
Hope this helps somewhat. Have fun!
