RIMS, anyone?

I was wondering if any of you have a RIMS setup. I would like to create one someday, or perhaps buy something that's prepackaged, but I'd like some feedback if any of you people have some words of wisdom.

Thanks in advance.......

A recirculating system can be a lot of fun. You can check out my personal site at http://sdcollins.home.mindspring.com. There is quite a bit of information there on the recirculating concept - mostly HERMS rather than RIMS.
Prosit!

I'm just about done building mine, it's a 3 tier setup so you only need a pump fo recirculation. I'll post pics soon.. It tooks several months and trips to the Mega Hardware Mart (plumbing), Sporting Goods store (propane stuff) and the LHBS (everything else). It's virgin run will be in the next week or two, still need to hook up the sparge arm, and wait til the Lager fridge is free...have to keep up the with demand for beer throughout football season.
