A few years ago I bought a Moth Mk2 RCM kit and built the case using some furniture board I already had. The build was made a little more difficult as the board was thicker than the specified materials so I had to do a few simple calculations and do a sketch with the new measurements. I made one or two slight changes to the extract ventilation area from the vacuum motor as I recall, to improve the air flow. All in all it all went together fairly well.
I have to say I was somewhat disappointed in the quality/design of some of the parts; for instance, the vacuum tube that sucks off the used fluid is made from plastic domestic plumbing tube and fittings. However, it works well.
It came with a fluid application brush, much like those carbon anti-static brushes only with much longer "hairs" and a small bottle of their own cleaning fluid.
One thing I like is that the vacuum tube is located below the record, which allows you to start cleaning side B whilst side A is being sucked dry. Due to the very loud noise of the vacuum motor in use, I tended to clean no more than a dozen records at any one time so as not to disturb the neighbours too much. You can get quite a good rhythm going after a while. I've cleaned around 400-500 LPs and around a 100 78's (different cleaning fluid needed for the 78's). I haven't got round to cleaning my 50 or so 45's yet.
Overall, I needed to change the velvet protective strips on the vacuum tube 4 times, used around 3-4 litres of fluids and an awful lot of new anti-static inner sleeves (from Covers33). I changed the fluid application brush once too, but that was because I dropped in my workshop area and it got covered in all sorts of muck. The vacuum tube is now beginning to wear and is a bit loose and floppy; I'm not sure if replacements are available for that though.
To sum up, it works really well (apart from the noise), cleans & dry's the records and never have I had such lovely crackle free playback.
