The wolf 3hp belt driven one on amazon is a good one for money has a 90 litre tank and have heard a good few reviews on it. I opted for a clarke Industrial 3hp 14cfm displacement one when I had a vat free voucher so much better than my old direct driven one. Whichever way you go take air feed from tank not the restrictive built in regulator.
This is mine in position before I wired and plumbed it in
