The SDRPlay is the perfect little accomplice if your radio has this feature. And at the current price of $149, it can't be beat. I wasted $60 on my first RTL setup, wish I would have went with the SDRPlay initially, but it was fun to compare different dongles.
I even tried building a protective metal box around the SDRPlay, just to see how it would help with RFI, but I honestly think it's just me living in an urban setting. It didn't really help, but did look cool

Ensure you are using a HIGH quality USB A to USB B cable with this device. Shielded & ferrite cores are a must, and keep the length as short as possible (mine is 3ft). Tripp Lite & Belkin make some.
The SDRPlay RSP is opening up new doors in ham radio, and I'm very interested to see where it will go! Firmware updates have been steadily and continually released since I've owned the device, and there's tons of knowledge already about the SDRPlay, so ask away if you get stumped!
I ordered mine from HRO, and it was here the next day. Ensure you've got the proper adapters or cables to go with it, the SDRPlay has an SMA female on the unit, I use a PL259 to SMA Male adapter to reduce stress on the SMA adapter on the unit.
On a side note, my preferred software of choice with the SDRPlay is HDSDR (for panadapter use) & SDRConsole (for SWL).
Probably the best $150 I've spent in ham radio yet. K5ACL
