So I'm on the fence about buying a second printer; I already have a CTC 3D Printer fully modded and printing great (albeit slowly); after some research I've narrowed down my selection to either a QiDi printer -- of which I've heard so many great things about -- and a Kossel Delta printer KIT from Aliexpress

vs

Kossel URL / Info (http://www.aliexpress.com/item/3D-Pr...524257967.html)


QiDi Pros & Cons:

PROS:

1. Great customer support
2. Already have experience with printer type (FF/Replicator clone)
3. Already have spare parts for printer type (from CTC)
4. I'm used to it

CONS:

1. $650 - 800 price range is a bit out of my available budget right now
2. Cartesian style printer, slow prints
3. I like new and different

Kossel Kit Pros & Cons:

PROS:

1. New and exciting
2. A kit to build! Fun! (I love making things)
3. Delta style printer, faster prints (better quality?)
4. Lower cost (within my price range)

CONS:

1. Sourced from Aliexpress, customer support questionable
2. Parts and build questionable
3. Bowden style extruder; can't print flexible TPU filament (or exotics) very well (or at all)?
4. Smaller print bed in the XY axis? (And I don't normally print TALL objects)
5. Have to make custom enclosure (additional expense)

Any suggestions or comments are appreciated, to help me make my decision, thanks!

P.S. Oh also forgot to ask, does anyone know or have experience with the Kossel / Delta printers? On the aliexpress site, I see some models with a "linear guide rail" type, and some with the "pulley system" type, and I don't really know which style of Z axis is better. Thanks.
