Romplers perhaps,but Depends which ones you get,I've grown bored of most Romplers of late but There are some superb hardware real analog synths around at the moment,things like the Alesis Andromeda, Moog Voyager/Phatty,DSI Prophet 08, or for weirdness and new ways of using sounds something like the Roland V synth,or Virus TI,ok there not cheap but they will outlast most if not all software and perhaps less frustrating to get working.
It doesnt have to be expensive owning a set of decent hardware synths,there are also some great secondhand synths too,you can pick up some real bargrains in the older generation of VA hardware,things Like the Novation Supernova's or KS Series,Korg MS2000,Roland JP8XX0 any of the older Nord leads,Korg Microkorg to name a few.
Each to their own,but give me a room full of hardware synths anyday of the week,and the exact problems you've been having is partly the reason why I stuck two fingers up to software and vowed never to grace my computer with so much as a software sequencer program again.
