The wee Strom is definitely a comfy bike, I've rode one, not for very long but it was comfy and the motor has very good low and mid power. The Honda Shadow series of bikes all have nice low seats, great motors and can be had for pretty cheap and are very reliable as well, or you can usually get an older ujm like a Yamaha xj650 or Honda cx500 pretty cheap off eBay, both are low slung, comfortable and offer a decent amount of power. There are a lot of bikes out there, just gotta ride a few to get an idea of what you're looking for.
