Thanks for the responses guys!
I have checked out the ones OTS makes even though their website makes me want to pull my hair out!
I can't see how they are much superior than the ASPE ones are. Their 1 color ones are relatively close in price, but from what I can tell do not offer a flash/cure so the product is done once it comes off the press. That is a huge negative. Once you step up to their "Mantis" line the flashes are there but so is like $5K extra that ASPE doesn't have.
I also checked out the Inkcups one, but that is a blatant knock off of the ASPE one, but they again added a couple thousand for their troubles. The communication I have had from them has also been lacking.
Spreading Ink- Thanks for chiming in with your user experience!! I really like the RapidTag, and they look like they are working on what I think will be the next "big" thing, their RapidTag XL.
