For me the key question is do you have enough space to go with separates, or must it be a combo machine?
If you have the space (and use of castors means often you can), then I'd get a pair of Multico's second hand - the 9" planer and 12" thicknesser.
I had a PT260 combo machine and traded up...and have been delighted. Incredibly solidly built, inexpensive (by comparison), beautifully made and have handled everything I've thrown at them. Generally £300-500 for a good one of either, so say £800 overall. Cheaper if you go for 3PH and run from a VFD (I do this).
The only downside I've found is that you can't get a spiral block, but that's going over your budget anyway.
If you must have a combo, I think the BAOS is hard to beat?
