If you look at the top of this page youll see a bunch of featured sales. The bottom row is all chips. Xenium, Xecuter, SmartX, and Xbit are all very decent chips and Im sure all but the SmartX have a solderless option. The SmartX most likely does as well. Im just not sure.
They all have great flashing features now, so you don't have to worry about hurting a chip via a bad flash. I have a Xenium, but that's just me. All are more then valid choices.
