you should probably check out arrowquip's new 74 series chute. Think it might be right up your alley with the movable head gate handle and built in vet cage. it's a little over 5k but i think it's worth it given the quality.
Actually, Arrow recently released a new squeeze chute that looks just like the 86 series but fits the 5-6k range. Think it's called 74 series - you can read about it on their website.
