I saw a 23CIII-XL with the VC head for about $70 on ebay recently. I picked up a still-in-the-box 23CII-XL locally for about $100. They are nice enlargers with loads of parts available - still made too. Should do 6x9. Carriers can be had on ebay for not too much.

However, I must say that I really want a Kaiser. Someday I'll get one new. They look really nice. Check into it though - it might not print the full 6x9 negative. I thought I read something about that somewhere...
