LPS Options

I have an SGC ST i5 hosting my Roons core.  Just saw a SGC LPS on the used market.  Are these units worth the expenditure?  Are there better LPS options for the SGC ST i5? I have the small watt SGC LPS powering my router and it appears to work nicely.  I dont think I have rebooted it since I hooked it up.  ST i5 has been stable as well but it has crashed a few times but otherwise purdy solid.
