Anybody collect Royal Albert China?

[ADraeger]

I'm actually not collecting.. I'm buying to use ( ), and I'm on the hunt for a teapot that matches the set I bought on ebay (pattern design is Derby, can also be paired with Heirloom or Alhambra).  I was wondering if anybody knew where I *might* find one.  The only seller I've found on ebay is Replacements LTD, and they are wanting at least $350.00 for just the teapot.   Thanks!  - Amber
P.S.  If you could refer me to some good books on collecting china, that'd be wonderful as well.
