Not sure how it is in the UK, but I went to a few trophy shops and ended up getting decent looking plastic bases real cheap, $1.50 each. (never hurts to ask around, as most retailers have different prices/inventory)

Oakwood are superb but remember you will pay a premium price for a premium product.
A good alternative can be found at www.­just-­bases.­co.­uk
