I am currently using a Bowden setup on my MendelMax. I chose this because eventually i plan on making this printer dualstrusion capable. For now i just have one extruder though. The main drive assembly is a MK7+ from FlashForge 3D printers. Although their extruders are barely capable of printing anything without babying the hotend, i had two of these I wasnt using. The drive assembly works really well with ~1.75mm filament, and is very compact. Initially i used the stock hotend modified as a bowden, but it failed miserably. So i invested in a JHead...two, but only one in use for now. The JHeads are great, and sport a 'standard' groovemount style mount. It was a dropin replacement to my old MakerGear hotend. Im still tweaking the slicer settings to work with Bowden style, but so far im very satisfied.

The tube is 4mm OD x 2mm ID PFA. PFA is a higher grade PTFE/Teflon material. I got lucky with a free sample from a local supply house. The fittings are el-cheapos from Amazon Industrial. 5mm threads with a washer and nute to trap it inside the printed parts.
I think this style extruder would work well on a Rostock or Delta style printer, because of its small form factor. Thought i would share. :)
