Focal reducer/field flattener

When I get my lens cell back from my 127ED (F7.5).. I'll be in the market for a Focal reducer field flattener of around .8x reduction.

I have looked at the WO type VI but am unsure if it is actually a reducer. Some advice appear to say it's actually an extender?

I have also looked at the TV RFL-4087, which appears to fit the bill although a little expensive considering the adaptors needed.

So should I go for the WO type VI unit or the TV unit? I am not looking at the WO type II as I believe it's mainly for around 600mm FL scopes.

Any advice appreciated...especially anyone who has either reducers/flatteners.
