I picked up some second hand Alpinestars SMX-4's in good nick off ebay for £45. Really like them, comfy, water proof, solid with loads of protection. Only had one low speed off in them, when bike slid down and landed on foot, just hand minor bruise on ankle for a couple of days. Only downside is the soles aren't as grippy as I'd like, occasionally my foot will slip on the ground, if it's wet or there's loose gravel.
