Help me decide what keyboard to buy

I am a guitarist looking to buy a keyboard. My local retailer has a Roland Fantom XA for $1099 regularly $1399 and a Korg Triton Extreme for $1299 regularly $1899, also they have a Korg X50 not on discount and a Roland Juno G not on discount, both are a little less than the XA or the Extreme. Played all of them and they all sound different but its so hard to judge in 15 minutes in a noisy music shop. I will be using the keyboard exclusively in the studio for now, and dont really need a sequencer or sampler. Would love experienced peoples opinions on what my best choice might be because I have no idea about keyboards. Also are there any other keyboards in this price range that I should consider? Appreciate any input, Thanks!

Just got a Korg TR from www.novamusik.com - $750, free shipping. ($1K everyplace else.) Their deals are so good this is actually the second synth (incidentally, the second Korg) I've purchased from them this month. Ask for Matt.

I'm a guitarist that started out playing keys 35 years ago, so I can relate to what you're trying to do - I think you'll dig the TR.

Can you elaborate a bit? My TR will be here next week.

I would go for the Triton EX if you just care about keys and sounds and not so much the sequencing/sampling, although it'll do both quite well. The EX I believe has something like 160MB of sample ROM. That's alot of sounds to work off of, I don't know how much is stock in the Xa, but I doubt it's even close, and Roland's SRX sound roms are ridiculously expensive. Besides, the Xa is very much a stripped down FantomX, the Triton EX not so much. More sounds, more effects, less corners cut. That's just out of those choices. Seems a waste to get something with sequencing and sampling if you don't plan on using them. I'd also look at the Yamaha stuff, the Motifs, S-series, etc. Maybe the X50 is the ticket, I've no experience with that one though.
