Last month I bought some Beato soft cases from musicians friend for about $80. Those have been working really well for me; they're not bulletproof, but as long as you're careful with them, they get the job done.
My cymbals go in a soft
Zildjian cymbal case for now and my hardware goes into a large, rolling duffle bag. The bag, the toms and snare for my kit, the cymbals and the rug fit nicely in my trunk and the bass drum rides in the back seat of my car. I try to gig about 2-3 times a month, and this works well for me.
I have to be honest though; that
Yamaha Hipgig is looking pretty inviting- 16" bass drum, the toms and snare pack into it, the hardware goes in the thrown... mmm.
So yeah... the soft cases are working well, but if you've got the money definitely go with the hard cases. They're a lot more expensive, but it's worth it just like any investment.
