Actually, Catholic wafers (and the wine too) are different.
In order for the Eucharist to be properly confected (I think that's the right word) there has to be first of all the correct matter - i.e. freshly made unleavened wheat bread made of pure flour only, with no additives other than water (no sugar, honey, yeast, oil, etc.). In Protestant churches you get any sort of bread - from French bread to homemade granola loaf even unto Saltine crackers. Episcopalian churches use jug port, which is improper because it contains additives (grain alcohol).
Then in order to properly consecrate the Host, a priest in the genuine Apostolic Succession (i.e. direct inheritor of the authority given by Jesus through ordination) must use the proper words and ceremonies of consecration as directed by Christ.
No Protestant church (with the possible exception of the "Old Catholics") is in the direct Apostolic Succession. The Anglicans/Episcopalians claim to be, but that is disputed because of the change in the words of consecration of Bishops under Edward VII.
While I respect your beliefs, really I do, we Protestants take communion properly as well. My Church does use unleavened bread, but the words used are quoted from the words of Jesus in the scriptures. I am not at all troubled by the method we use, just as you are convinced your way is correct. I do think God honors us all.
