Sorry stubbs, you asked if there was a cheaper way to do things, and I completely missed out on answering that.
Yes, there's a much cheaper way of doing things. You should be able to buy 4 or 5 Chinese or Indian capes for the price of a good metz cape.
Cookshill do some okay budget materials.
Cookshill Fly Tying Materials
But no matter who you're buying from, email or PM them first and just explain what you want, the sizes of flies you want to tie, and they'll be more than happy to send you what you need.
If anybody tries to tell you that you are better off spending more money on capes then they're either deluded or trying to sell you more expensive capes.
