Been using VueScan for years and years now...it keeps getting better and is hands down the best application available for reliable scanning on a Mac. I was so tired of trying to get the twain function to work in photoshop, so glad I found this application. And if a good running application isnt good enough, the support is among one of the best Ive experienced. I dont know the developer, but think a good product, with great support deserves praise.
