Not going to agree with P-J on this...
1. Compression fittings are NOT easy to do without the flaring tool... If you don't have the tool, you'll need to get one. They are NOT cheap either. By the time you get that tool, you've spent more than you would have just buying a pre-made IC...
2. You don't NEED to get the expensive bender to make the final bends to the outside of the pot. They also have tools that are essentially springs that slip over the copper and allow you to hand form them. They come with several sizes in the package, so you can use them for other sized tubing too (later)...
I did try to use compression fittings on my IC... Could NOT get them to seal up at all. Gave up and just slipped the hose over the copper tubing. If you use the hose clamps properly, they won't leak one bit... Plus, changing the way the IC is setup without having compression fittings is easier. If you mess up the compression fitting when you're putting it together, forget about it...
Unless you're a plumber, or someone that's done MANY compression fittings in the past, I wouldn't go that route at all.
Use good strength hose/tubing on to connect the IC to the water source, and carry it away, and you won't have any issue. If it really was such a poor way to connect, the majority of people here would be using compression fittings, instead of the rare few. If you use the cheap vinyl tubing/hose, you could have issues with it... I don't think I'll see that happen, considering the host I picked... I'll probably use it on my next IC too.
