We purchased the NuWave cooktop at Kohl's last year - I think I got it for around $60 with coupons/sales etc.
I think it's one of the best purchases we've made for our MH, and my husband actually agrees! We use it almost exclusively, as it heats up most things just as fast as the gas would, without heating up the entire interior. Also, we use it outside as well, in place of our propane camp stove, as it's much easier to set up.
A few things to remember -
1. you have to buy special cookware that is induction ready. it can be expensive depending on where you get it (we ended up at Ikea, bought a few pots/pans and they work awesome)
2. The heating/induction area is only the small (about 6" diameter) circle in the center, so even if you have a much larger pan, that is the only area being directly heated. It can take a while for a large pot of water to heat up.
3. It uses a lot of electricity, so I'd not recommend it for boondocking, only when hooked to power or on a generator.
So, there's my experience - let me know if you have more questions!!!
