Yeah, I nearly bought a Rostock, but like you said, it’s a bit expensive.
So that Kossel mini looks pretty good, as long as you don’t mind that the bed is pretty small. It has a E3D V6 hotend though, which is widely considered to be the best hotend (within reason) that you can get. I’ve used low quality hotends, and rightnow, I’ve got a Prusa i3 with a E3D Lite6, and the print quality jump is amazing. The hotend/nozzle/extruder can make a HUGE difference. ALWAYS go with E3D if you can.
The dimensions are reasonable, so you shouldn’t have too much trouble with things like belt stretch. Does it come with pre-loaded firmware though? The Duet is a great control board, but it would be a huge pain to get all the firmware setup for a delta.
Have you considered a full size Kossel? It has a much larger print volume. I know that Folger Tech sells a pretty good one for $325. It has an aluminium extrusion frame, which allows for very high rigidity (which is super important). You may need to upgrade the control board if you want a screen though.
But, if you like the Think3DPrint3D Kossel mini, by all means, go for it. It looks like a pretty good printer 
Great!
I was also searching one for a few days, as a friend was looking for a delta, and saved this link.
You will order this one? If yes we would be keen to see how it will print.
And if you need any help let us know we are here to help. If you don’t know something or anything unclear ask it first.
I can also help you with the first steps when you finished assemble the printer, like firmware calibration etc.
I think you’re totally right…To build my first printer on top of making a ton of upgrades would be too much. I’m going to go the kit route. I do want a big build size but i’d rather consistency and ease of use. At this point i’m just looking for the best starter kit i can get for under $800. I might end up going with the folger tech. These are the kits i am also considering.
This one looks to be the best: http://www.aliexpress.com/item/Package-B-auto-level-k800-kossel-mini-Reprap-prusa-rostock-cheap-3d-printer-machine-kit-with/32480543201.html?spm=2114.30010308.3.387.PNcQBh&ws\_ab\_test=searchweb201556\_0,searchweb201602\_2\_10017\_507\_401,searchweb201603\_3&btsid=f5664ace-4b17-427d-895d-72d5476aba2f
This one looks great as well: Duet 3D
The think3dprint3d kit is probably the best delta under 800. but actually, I think seemecnc is having a sell right now on their kit. I personally would stay away from aliexpress kits.
actually, yes’ $851 on seemecnc.com
I am a bit hesitant on the aliexpress kits…as doing a google search for Renren 3d printers yields next to no support or reviews. Maybe they would be willing to send me one for free to spread the word 
And that’s a great price for that seemecnc printer. I’ll keep that option on the list as well.
Awesome, thanks so much for all of your help. I’ll post back here when i get my printer.
