The tumblers are great, a good friend has a mid sized one but his has two drums, absolutely wonderful bit of kit, he dry hangs his plants then tumbles them to remove the leaves (Great thing is that the leaves only get trimmed and not the bud due to the size of the slit holes to cut leaves, then swaps over drums after and then collects the kief from the other drum, he gets around 200oz done a day including kief, not so bad really, all in one machine and only payed £250 for it brand new, stands around 4ft tall and 3ft wide, legs are adjustable to so if you want to work with a pc chair you can at what ever height you wish.
Its had 1 problem in its life and that was a bearing which cost £1.50, will find all the info out on the machine but im pretty sure they do a small version of it to which is around the same height as the other in the comments, maybe a little more expensive due to the extra drum though.
