3 ballasts for dual 55w power compacts complete with linear endcaps (not square CSL type pattern). $30 each, no reflectors or bulb clips (although if you buy them all, I'll throw in 4 bulb clips and a reflector). They were in use for about a year and a half, till I took that tank down last year. Since then they've just been collecting dust.
Hanna Phep hand held ph meter w/ temp (model # HI9812

that I used about 10 times before I no longer needed it. I'd like to get $50 for it, I feel it's an excellent deal as I barely used it. It too has been sitting collecting dust for the last year. I have a packet of PH 10.01 and a packet of PH 7.01 calibration solution for it.
ETSS Super Reef Devil 3 protein skimmer for $50. It's in perfect shape and I loaded it with new bio-balls. Its a discontinued model, although they swear its not due to lack of performance or problems with the unit. I think it was rated at 150g, although I feel and have always felt that was stretching it. I believe they said it should be ran with a Mag5, although I used a Mag7 throttled down a bit. It preformed excellent on my 54g corner w/ a 30g sump for the 2 years I used it. Its touchie, ie. shuts down even with a single finger enterring the tank and adjusting it is finicky. Its just been collecting dust since the tank was town down.
Garmin hand held GPS 3+ complete with 2 MapSource cd's (US Topo & Roads and Recreation), dash mount, carring case, serial cable computer link and 12v auto power plug. $150 takes all. Its in excellent condition, no scratches or blemishes. I only used it in the car on road trips.
