vinnie90 - I would suggest to buy a printer that is simular to your as much as possible. That way you can keep slicing programs and setting the same and not worry about what machine your going to use and what setting work the best.

augustaht - @we3du: hehe good point. I guess I was just wondering if there was greener grass out there. Although I'm mostly happy with the replicator 2, it's not a husband or anything. That is, I wouldn't feel qualms ditching it for something better. :-)

Though I suppose that the devil you know > than the devil you don't.

@vinnie90: that is a really good point. I hadn't considered that.

sd3dprinting - We service printers from seven different manufacturers. Here is how I would rate them in order of preference:

1. Airwolf XL - Pros: reliable, easy to calibrate Cons: one nozzle, high vibration
2. Ordbot Hadron from Punchtec - Pros: reliable, fast Cons: difficult to change filament
3. ConnectXL from Punchtec - Pros: fast, large build Cons: poor electrical design
4. Flashforge Creator Pro - Pros: enclosed, ease of use Cons: small build, closed software
5. Printrbot Plus dual extrusion - Pros: large build, simple Cons: poor electrical design
6. Tricolor from RepRapPro - Pros: three extruders Cons: unstable build, difficult to calibrate
7. Replicator 2 from Makerbot - Pros: ease of use Cons: closed software, small build
8. MH3000 from ORD - Pros: up to four extruders Cons: nearly impossible to calibrate

raykholo - sd3d - talk to me about the poor electrical design of the Printrbot Plus. I used a single extruder model last year and am very curious what the issues you've seen are.

sd3dprinting - Issues so far with Printrbot Plus: bed frame arrived cracked, a replacement was shipped immediately. Bed cannot sustain temp above 90C during print. Second extruder relays thermistor value but will not heat at all. Belts arrived assembled very loose, requiring minor maintenance to print successfully. Probe thread pitch is way too large, making it a pain to calibrate.
