Wanted to comment this on the previous Blue Compass mic arm deal I posted here https://www.ozbargain.com.au/node/716568 but can't comment there anymore.
I know the Brateck MDS-01 is a popular half priced clone to the Blue Compass, but seems like it keeps going in and out of stock.
I found another clone of the Compass it's called the Kensington A1020. Cheaper than the Compass all the time, but might help someone find a deal if they keep an eye out for a price drop on the Kensington.
For reference I paid $65 for the Brateck when it was reduced on Amazon AU.
The $20 no name eBay cheapie I got over a year ago is still holding up well
