I own a few of the titles mentioned and always on the lookout for others if the price is right. A few of the asking prices are way out of my reach, see below.
Solid State Design for the Radio Amateur by Wes Hayward and Doug DeMaw is priced between $91.00 used or $300.00 new on Amazon. But you can pick up a new copy of Experimental Methods in RF Design for $30 and change, also at Amazon. The ARRL store price is $49.95.
Pays to shop around and save a few buck$.
