3rd Party Memory Expansions for 3/50?

[John Tebbutt]

Has anybody had any experience with 3rd party memory expansions for the
3/50 ?  I'm currently considering offerings from Parity, Helios and
Clearpoint. Doe one have anything good, bad or indifferent to say about
any of these products, or any others ?

The kind of board I am most interested in is a 4MB RAM expansion which
does not require soldering for installation.
