Check w2ith Lefty Hi-Trak (I think that's the right name) - he quite often has really good pricing on last year's styles in dexters. I've bought 2 pair from him - one I wear all the time, and a second for when these give out - since I know I'll never see 'em at that price again.
and - I would highly recommend the SST Vs instead of 1s - and here's why - if you step in something you can change your sole. Easily. I've done that a couple of times now, and instead of having to throw the shoes out, or finish a set in a house shoe, I can change my sole and get back on the lanes.
Also - one night I bowled on a pair where the majority of the approaches were fine - but the spot where I needed to slide to pick up a 10 pin was so slippery I could barely stand up. quick change to the less slippery sole for my 10 pins, and I had the advantage back. Well worth it.
