I’m not familiar with this one.
This topic always spurs debate, but I’ll just add my $0.02 in your price range.
There are obviously LOTS of good, high quality mics. But, if you’re looking for something inexpensive, I’ve had great luck with this one:
Shure PG 81 (http://www.shure.com/ProAudio/Products/WiredMicrophones/us_pro_PG81-XLR_content)
Its an entry level mic for Shure but it sounds good and has worked well for me with pipes in the past. I know fiddle and flute players who use them as well.
They can be had on Ebay, brand new for ~$80 - $90.
I always try to use dynamic microphones because to my ears condenser mics produce a flat and somehow squeaky sound when recording reed instruments.
I use a Sennheiser e608 (dynamic) for taking up pipes and whistles as well. Sounds quite good. Not perfect, but in exchange it’s low priced. 
yep. this will be a neverending story…when hunting good sound …with low costs
From the link:
It is ideal for use as drum over heads, hi-hat, snare, or acoustic instruments such as guitar and piano. The M37 features a high SPL rating of 137 dB and is capable of capturing even the loudest of audio sources.
This might be why a good many pipers have said that a large diaphram condenser mic is well suited to the pipes. This M-37 seems to be somewhat uni-directional, as opposed to the more popular omni-directional mics that have proved popular with the pipes.
