I have used a few:
Lyman Universal
Forster with the 3-way head
Hornady
Henderson
Notes:
Lyman Universal:
Is a trimmer with a very cool case holder - sort of a quick insert. This makes it pretty quick to move cases in and out. The negatives are: it doesn't chamfer, so you need another tool for that, and it's hard to make minute adjustments. The only reason I keep it around is because it's the only thing that I've got that can trim my 37XC. You need to buy the power adapter for it.
Forster/3-way head:
I love that you can use the 3-way head to chamfer the inside and outside of the neck and trim at the same time. The negatives are that it is relatively slow to use and does not make minute adjustments easily.
Hornady:
Meh all the way around.
Henderson:
Love, love, love this thing - a precisely machined piece of equipment. Powered, quiet to use, quick to cycle through, very accurate, and easy to change for different cases. Negatives are that it is expensive, and it is expensive. Did I mention it is expensive? Of note is that it indexes off of full-length vs the primary competitor, Giraud, indexing off the shoulder. Which one is better? Unknown.
Out of those four, given your budget considerations, my recommendation would be the Forster.
