I need help deciding on a trim machine or should i make one?

I am looking at the spin pro trimmer/magic trimmer/tumble trimmer. They all appear to be pretty much the same thing. It seems to me that this design trims closer then even a trimpro. I also see people making them online. I have seen a good design with fan blades and one with weed eater line. Just looking to see if anyone has used any machines or has any input. Can the spin pro do large colas?

im interested in the spinpro also. everyone i know of has bought the rototrimmer thing and they love it but its so expensive. the dispensary down the road will rent one to you for a mere $350 per day LOL i like he spinpro idea personally, it will do about an ounce at a time so even a decent sized grow room shouldnt need to spin that thing more than a hundred times. the price is attractive at around $500. go on youtube and watch video on the spinpro and others, i believe the biggest nug you should place in any of the trimmers is like 75mm.

theres a good thread on diy trimmers in the diy section. they were trying to make them out of box fans.

I have a spinpro. Doesn't work great on huge colas. In fact I wouldn't recommend trying to put a big cola in it. But it's a godsend for medium and popcorn sized buds which is where most of the trimming time is spent anyway. It's real easy to clean, straight to the dishwasher which takes care of the top and bottom pieces of the unit. I put the middle screen part in the dishwasher also but I usually clean that with alcohol as well after the dishwasher since that part usually has a lot of resin stuck to it. You can get them on ebay for under 400 if you keep an eye out. I got mine (spinpro brand not a generic) for 380 shipped on ebay.
