get the short pyton.. then go over to the hardware store in the bulk hose section and pick out some hose.. you can make it as long as they have hose!
LOL
Depends on the situation Bill. We are in a perdicament right now with trying to make a home made Python. After going to the hardware store, it would have definately been cheaper just to buy the bigger Python. Considering that the hoses were $.82 per foot, we needed 150 feet. Thats $123 for tubing. Then the additional parts. So instead, purchase a 100 ft Python for $63 plus the 50 ft of tubing for $41 and round out at $104. BUT, we couldn't imagine spending that much for water changes so we just bought garden hoses.
LOL Weird setup, but it works.
