I have done the single super compact (1x12) thing, then two super compacts, back to one super compact. In the end I missed the fuller sound of having 2 speakers so bought a super twin as it's the best of both worlds, 2 speakers, one cab and not that much bigger than a single cab. I also think it looks better than stacking two cabs vertically. Small footprint onstage (remember them!)
If you did want more of an old school sound, the 210 would be a good option. You can stack 2 horizontally, as intended and it looks pretty good. Having 2 cabs will cost you more obviously. 2 super compacts s/h will cost roughly £900 and a super twin will be around £650 for essentially the same thing. Having 2 SCs/210s gives you a more flexible, modular set up and the Super twin is a fantastic one cab solution.
