0.65mm pitch, no problem. I've hand soldered TSSOP packages deadbug style, with flying leads connecting the pins. Tricky, but you just need a steady hand and some skill at soldering (if you're a beginner, maybe you should shelve them for a few years while practicing..?).
Cutting traces on copper clad isn't terrifically hard: you only need to make one narrow trace, then an outline of cuts around the area (to form the four corner pads and cut the center trace loose) and one cut down the center (to split three pads into six). A sharp utility blade is the best way to go.
If you're in the habit of getting PCBs fabbed (or making them yourself, if you can get the consistency and detail), no problem at all. Easiest way to install fine pitch: tack it down, flood with solder (relatively speaking), then wick out the excess. Just enough stays on the pads.
If you wanted them for just 2N3904 sorts of purposes, that sounds like a lot more work than you need for just playing around (let alone breadboarding!). If they are RF transistors, working with RF is kind of a pain anyway, so it'd still be a good bargain.
