Any reason not to get this?

Any reason not to pull the trigger on this-

Brew Logic Dual Tap Draft System- with Reconditioned CO2 Tank :: Midwest Supplies Homebrewing and Winemaking Supplies

I may be moving in the next two months so I don't want to drill a fridge or do a keezer until I know what kind of space I'll be working with. Plan on keeping the picnic taps for now and just open the door to get my brew.

Any other extras I should get?

Looks like a good deal to me, only thing missing is the beer

Perfect solution for your plan, and a nice setup as well! The dual pressure regulator is really handy for carbing/serving, the only thing missing is the shanks/faucets. Once you figure out what you're going to do there, it'll be an easy addition.

instead... at the same price.

Same thing, but with a new CO2 tank (they are phasing out reconditioned tanks)

I bought this system, and have had it running for 3 weeks now with no problems..

Extras to buy....
2 sets of O-Ring Set :: Midwest Supplies Homebrewing and Winemaking Supplies
Keg Lube :: Midwest Supplies Homebrewing and Winemaking Supplies

My Brewlogic rig

+1 on Arkador's suggestion.

That's what I got three weeks ago, as well, with the same additional extras. No problems whatever, though I had to re-seat the "Out" poppet on one (it leaked beer when I applied pressure). I'll be installing the whole kit & kaboodle in a fridge this week, as I'm getting a dedicated kegerator.

And even if the brew logic regulators are "homemade", they seemed to do a fine enough job.

I have the same one, and did have some problems with regulators.
Called Midwest and they sent me a new one.
Works fine now.

I bought the Brew Logic Single Tap setup from Midwest. They were great. The keg arrived with bad gas post, but a phone call had a new one to me in a day or two. No problems at all. And at $150 for everything, including a new gas tank, it was a great price too.

Ordered today...

Good luck w/ the purchase. I actually have been using picnic taps for two years now in my keezer. They work great, I also like the fact that the tap stays cold so the nasties don't take up residence quite so easily. Simple and easy to clean too!

I was wondering if anyone had attempted a DIY plastic keg like the one from this link

and if so does anyone have any thoughts on using a CO2 bike tire inflator like this one?

I have the set up from Midwest have had no problems with it and love kegging my beer. I had an old (last hydro was 1988) 20lb CO2 tank just "laying" around from an old job that I use instead =)
