It really depends on how much work you are planning to do. I have used most every method you mentioned. I am doing the most work I have ever done now. I just bought an 11x14 Versalab archivial washer and I love it!! I did 80 8x10's in it this weekend. If I were using the "rapid tray", I'd still be washing them. The Versalab washers are on sale right now and the 11x14 is @$190. It is pricey, but in my mind it has already paid for itself with convenience, speed, and ease of use.
