I hadn't appreciated that they record on mono tacks so I may look into an 8 track. Having said that, I may just stick with a 4 track and upgrade to an 8 track if I enjoy recording in analogue.
I am doing it just for fun really. I love recording music and I love trying new methods and idea. If I am honest I've never been too fused with certain sounds or quality. I just get a kick out of the process of trying new things and experimenting with ideas. And recording in audio has always fascinated me after I watch a Pink Floyd documentary.
Cool, that's pretty much what got me into it too.
Just one more question. Can you use any mixer with a reel to reel? What connections do you use to connect the recorder to the mixer?
Pretty much. The crazy expensive ones might be XLR-only, but most of them - particularly the ones within affordable reach - will have a combination of XLR and 1/4" jack inputs.
The Tascam 388 I mentioned because it is a combination mixer/tape deck, but most other TASCAM or Fostex machines will have RCA/Phono connections on the back. If you're going to mix analogue-style, you would need an 8-way cable loom/snake with RCA plugs on one end and 1/4" jack on the other. This will allow you to plug the outputs of the tape deck into a mixer.
If your aim is to mix digitally, the mixer may be less important. Typically it's used to mix the outputs from the multitrack to stereo, which the computer would be doing instead. However, I've found it's handy to have a front-end mixer to connect the instruments to. If this mixer is connected to the inputs of the tape deck, you can use it to do some kind of channel routing instead of having to constantly plug in and unplug things from the back of the deck, which I believe is what mdainsd was saying.
Alternatively it might be a good idea to get a patchbay - that way you'll wear out the patchbay's connections instead of the ones on the machine itself.
8-track decks to look at (besides the 388) include:
1/4" 8-tracks:
Fostex M80 (older model)
Fostex R8 (1/4" 8-track)
1/2" 8-tracks:
TASCAM 80-8 (pretty old now)
TASCAM 38 (48 and 58 as well, but I believe they're XLR connections)
TASCAM TSR-8 (only has two heads, can't do the record-through trick)
Otari 5050-8 (XLR, may require pin-reversed cables)
...of these I've used the TSR-8 personally. It's a nice machine, though 1/2" tape is a little expensive.

This was my first setup, the left-hand mixer was for the instruments, the right-hand mixer was for mixing to tape.
The machine in the middle is the TSR-8 and on the far right, a TASCAM-32 which I was using as the master recorder.
