Hi , I installed the Incognito on my rb 300 arm two years ago. Pretty straight forward and easy to do . I used the upraded cardas clips for the cartridge connections. Very happy with it . I personally did not think it was overpriced when you take into conscideration how good of a sound upgrade it is for the money and you get everything you need to do the job. I think I paid 175 US 2 years ago.Some good reveiws on the net. Cheers!
