Question about Marantz Remote controls

I've got a Marantz SR5200 and for some reason I don't have the remote (don't know how that happened but it did). An original is more expensive than the current value of the unit.

Is there a relatively inexpensive universal or programmable remote that has or will accept Marantz codes?

Any help, guidance or input would be appreciated.
You may want to try the URC R-6 universal remote availible at Best buy. I have used it with Vintage Luxman and Nakamichi gear with great results. Best news is its 20 bucks.. Good luck
just get a Harmony One, all of the codes are already on website database.
music direct has had some marantz remotes on sale for 29 dollars.
