A few points on this model (Type VIIc in 1:72 scale from Revell)...
1) For those located near "Hobby Lobby" stores (
www.hobbylobby.com)... please note that every 3 months or so, these stores have 50% off all plastic models. And, some of the stores do carry this kit (several Hobby Lobby stores near me do).
If you can't wait for 50% off, sometimes Hobby Lobby provides 40% off ANY item in the store. See their web site for coupons and sale details (which are updated every week by Monday).
2) There are several aftermarket items for this kit, including photo-etched decking (see White Ensign Models - although I beleive there are others also), interior pressule hull parts, crew, etc. Also, there are "Water Tight Cylinders" available for creating a fully operational RC model using this kit.
