I've gotten transfers from Transfer Express. Good quality but a little pricey. Is there anything out there that will give me comparable quality at a lower cost?
With a few minor exceptions, everybody. Transfer Express is the most expensive transfer maker by a large margin (except for ENV), anywhere from 2.5-4X the price of other quality printers.
If you aren't in a hurry, First Edition is the least expensive. Dowling is also inexpensive but slow. Ace is not too expensive for basic transfers but their pricing matrix is complex and they have hefty ganging charges which put them among the most expensive. Ace does not do 4 color process. F&M is inexpensive and fairly quick, they also offer 4 color process. Versatranz is very quick but a little more expensive (but still less than TE). I chose F&M as my standard, with Versatranz as a backup for quick turnarounds and Universal for my digital transfers.
There are other transfer makers out there but I am less familiar with them... like Howard and KE.
