The '65 Deluxe Reverb is a reissue ( 22 watts, one 12" speaker ) that can be cranked to get a nice smooth tube overdrive and can be used for smaller live venues.
There is a series of reissue '65 (blackface) Fender amps: Deluxe Reverb, Twin Reverb (85 watts, two 12" speakers), Super Reverb ( 40 watts, 4-10' speakers). The reason they were reissued is that the original amps are prized by guitarists. The reissues are pretty good amps, the originals ( blackface or later silverface ) are better. I have a '74 Super Reverb I bought new in ...1974 ! I used Twins many times in rehearsal studios through the years. I've tried the reissue Super and now use a reissue Twin at my current rehearsal place; they're nice amps but the originals sound better to me. If you really want a Twin, take your time and find a used Twin - it will be well worth your money. The reissues will not hold their value over time as the originals have (point to point wired amps can be easily repaired; circuit boards are usually tossed). Just bear in mind the Twin stays clean almost dimed and is VERY loud. Also, there is a "Twin" amp (AKA the Evil Twin) that is not the same as the Twin Reverb.
