ASW15 is a good option - but be aware that anything around that sort of price probably won't win any presentation awards.
If you can find a little more money an Astir of some description would fit the bill. Or, buddy up with someone who flies at opposite times to you (if your both mainly weekend then a midweeker and vice versa). Midweek could work even better, they share the aircraft during the week and you get it exclusively on weekends. Find 2 other likeminded people and all of a sudden there's 15-18k in the pot, which will get you a nice ASW19, DG100/200, LS3 or other go-places machine. Not to mention a share of all the costs (Trailorage, insurance, maintenance etc - generally the costs don't go up at the same rate as the aircraft, so 3x the budget doesn't nececerally mean 3x the operating costs).
Chat to your CFI and see what he says - some clubs have a rule along the lines of all purchases must be vetted by the chief for suitability (protects you and your investment, and early bronze pilots going and buying a pup/something that will kill them).
The Schweizers never really worked in Europe, there was no point importing mahogany bombers when you can go to Germany and get the same product. The Solo got canned by Derek Piggot and never really found any real success, possibly as a result.
