Hi,
I'll get you some height measurements on the Co2 tanks Monday.
On the Schuran, most people use Maxijet 1200 or Aqualift to feed them, I think we had used the Aqualifter without a problem.
We have sold a lot and very few issues with them. The few people that needed parts, was usually some type of accicent and something got broke. I think we have only ordered parts for them 3 or 4 times in the last several years.
That said though, Schuran customer service is not "customer friendly". They don't like to answer any questions or problems, they'll tell you to talk to your dealer. We can special order just about any part, but they do even give us a hard time, they don't like to ship small packages international. Our last customer we ordered a part for had to wait about a month to get his part and after shipping and the part, ended up costing him 100 bucks.
So your odds of needing factory parts are probably about 1%, but if you do, that does make this closeout special deal much less attractive because of the wait and cost involved.
When Schuran first came to the States, I think it was far superior to all the other reactors out there. I think GEO in the last couple of years has really strepped up in quality and performance and really a GEO today, should be as easy, if not more easy to setup and run then Schuran.
