a little more than 600 Riyals for a keyboard with weighted keys. The brand is really irrelevant cause if it has midi outs and midi control someday she or you will figure out how to hook it up to a pc and use vst synths. Really, I'd suggest getting an 88 key HAMMER ACTION midi controller and just hook it up to a computer and run some VST piano emulations. It might cost a bit but you won't have to deal with upgrades later.
