got mine from marinedepot.com for $16.99 in USA via border pickup but eheims 600 ( and as mentioned, maxijets particularily the older model 400 ) would also work provided you pull out the nozzle from the old RSM pump and insert it into a short vinyl standard 1/2" diameter tube.. leave pump dangling to desired height ..... reduces microbubbles as well. The eheims are also more powerful and adjustable.
Check out other sites for more info such as reefsancturary/ nano-reef.
