Looking for a good phono preamp solid state...

As Colitas noted the Rogue Stealth is very tough to beat at just over your price point. The Dynavector P-75 is also quite good, especially if you are using a Dynavector cartridge. Personally, I'd stretch for the Stealth over any other new or used sub $1K SS phono pre that I'm aware of.

Lehmann Black Cube is a good choice, I upgraded to a Primare phono stage a while back and like it plenty. Both are good choices and meet your budget (used)

I found an Aragon 47k with the IPS a few years ago and have been very glad I did. Around $350. or so if I remember correctly.

Looks like I made 2 mistakes...

1) Not seeing that Mfs was looking in the sub-$500 range

and

2) Giving the impression that I was trying to be the "forum police" - I wasn't. Just thinking that he would get more answers in that forum because phono preamps deal specifically with....phono.

Anyway, back to the original question:

I've listened to the Musical Surroundings Phonomena and it is great little performer for it's price on the used market. The Lehmann Black Cube SE and Mccormack Micro Phono Drive fall in the same price range.

The Grado PH-1 can be had for $500 new.

Also, the Benz Micro Lukaschek PP1-T9 can be found at the next step up in price, ~$650.
