For the SQ such a Technics would give you, that'll be hugely overpriced.
I wouldn't venture to guess the SQ of that particular hugely-modified 1200, but I am in the group that happens to like the SQ of the stock 1200. Granted, when I bought my two 1200's (I bought them both brand new a few years apart from different vendors), the combined cost (including shipping) was less than $1000.
I have no complaints and no regrets.
