The RUMBA board has a design flaw, which is that the mosfets it uses are not intended for 5V gate drive.
This, and it also drives the indicator LED from the signal line, making the signal substantially slower, resulting in higher MOSFET heating.

Most people will be satsfied with IRLB8743 or IRLB3034 MOSFET's unless they spend a lot of money on a good SSR.
Don't be surprised when you open such a "good" SSR and find an IRLB8743 inside :-)
