Kubla, A RtoR Deck can be a very nice item to have.
I have two, a bought new mint TEAC A3340S, and a mint TEAC A2340R. Both are 4 track, 4 channel decks, but either can be used for stereo playback-recording.
I've yet to hear a cassette deck to compare to a good reel deck. Nice decks would be a mint Revox A77, Tandberg, Fostex, and TEAC/ Something like a TEAC 3300 series with both 7-1/2, and 15 ips would be sweet.
There is a two track version in this 3300 series, but the downside will be it won't play 4-track tapes.
Many of these units had auto-reversing, using a piece of foil tape applied at the end, so it would reverse, and play the other side, without havinbg to get up.
At the slower speeds (7-1/2ips) with a 10" reel, they're great for parties, putting a mix of music on them (remember Pulp Fiction?) and also great for recording LPs. After you record LP's onto them, don't matter how loud you play them, or people dancing around jumping up, and down on the floor, you won't have to worry about acoustic feedback, or transmitted vibratrions.
