Tray developing is actually pretty easy with up to 4 sheets at a time. Just practice in the daylight shuffling sheets untill you can do it smoothly.
I use a JOBO processor, one of the older CPE-plus2 models. I use the older 2500 series tanks that allow 6 sheets to be developed at one time. This provides very consistent results for all my normal and N+ processing. I rersort to trays for any N- development.
JOBOs can be found in near new condition for very reasonable prices on Ebay all the time. When I first purchased mine a wondered if I would justify the cost, but have paid for it many times over with consistency and convenience of being able to process 35mm up 8x10. There are numerous posts on the photo.net film processing forum archives discussing JOBO.
