Coma Corrector

[nitram100]

Hi guys, 

Been looking at buying a coma corrector for my F.4.8 Newt in sig. It will be strictly visual use and was wondering which is the best bang for buck out there? 

I've been looking at the Baader mk3, gso, explore scientific one etc I can get the Baader MK3 for £122.

Thanks for any advice, Mart

I use the Televue Paracorr and with patience you can get mk 1 versions for about £150 used. I really rate it but have not really used the others apart from http://stargazerslounge.com/topic/206099-altair-astro-coma-corrector/ which was pretty good.
