I brew on a propane fueled 3-tier system in the garage. It's simple, but does just what I need. Even brewed a couple of award winners on it. By this time last year, I had already used two sacks of base malt (doing 5 gal batches). This year we're already consistently in the 100's every day, and I just can't do it.
My "local" HBS in the Ft Worth area just put the Grainfather Connect on sale for $799, shipped free with an AG kit thrown in to boot. I'm a little leery on making the switch, as I know my old system so well. But man, the thought of being able to brew in the house through the summer was too much to resist. I've done quite a few BIAB batches in the past with good success, so I know the basic process. Plus, I have a few buddies who have them, who can help me out. I'm keeping my old system, and it will remain my "cool weather" rig.
