I bought a PowerSpec Wanhao Duplicator Prusa i3 Plus and am quite happy with it (see https://www.microcenter.com/product/486543/wanhao-duplicator-i3-plus-3d-printer ).

Several things to consider:

• There are a LOT of great 3D communities for 3D printers; check out "Wanhao" on Thingiverse to see parts you can print to upgrade your printer(s) ( http://www.thingiverse.com/search?q=wanhao&dwh=995d35d8e0e03d1 ).

• Check with your local makerspaces (Houston has 13 Makerspaces, I'd check with the major ones like TXRX Labs ( https://www.txrxlabs.org/ ) who not only can advise you on printers but may actually sell kits made by members.
