I think you'll do a-ok with the CR70. It may not have three gauges but it's not like speed matters anymore. Test enough delta tubes and and you'll only have to look at the book briefly if at all in most cases. I'd say your CR70 was a fairly decent bargain, many sellers really try to soak for them.

By the way, try an arts and crafts supply store for the foam.
