We bought our first horizontal last October, a Haas EC-400. I looked at the EC-300 first, but came to the conclusion that it was too small for our needs, and was limited to 45 degree indexing on the pallet unless you buy the 4th axis option. The EC-400 has standard 1 degree indexing, handy for angular features. Make sure the machine travel and pallet weight capacity will do what you want.
The EC-400 has been a fast, reliable machine. Our EC-400 ended up at 175k, with tax and all tooling (including some very nice Chick tombstones), sitting on the shop floor. Hard to beat that.
Good luck with your decision.
