Ah, if you will be back in the States, get the 23C if 6x9 is as big as you'll go. If you go up to 4x5 Omega, Beslar, Devere and LPL are all fine enlargers to consider. The 23C or the Omega D2V would be my low cost recommenation $100 or $150 will get a nice one with a good collection of lensboards, neg carriers, etc. Good luck. China is the most amazing place I've ever been to photographically.
