Have you tested their filaments? Printing with ABS filament is fairly straight forward; although compared with PLA, a heated print platform is required. Remember that the first layer is bonding with the print platform. If the print is not firmly attached to the platform, the print will fail. Anyways, I got 12 spools of ABS filament in a Saver Pack deals at 3d2print.net for only €299,95. So far, I never had any issues with melting point.
