9mm nagler vs 10mm speers-waler

I am in the market for a wide FOV in the 9-11mm focal range. I would like to get the best EP but only spending $150. The new speers-waler 8 element 82' FOV is inticing for $129 but how would it stack up to a used 9mm nagler type1? Should I bite the bullet and purchase a type 6 for another $100+? Could I even find a type 6 used at this point?If so how does the speers-waler stack up to the type6?
Your thoughts
Thanks
Todd

The 9mm Type 1 sits farther back on the focus plane and has decent ER but not great for eyeglass wearers. I find it to work great with refractors and gives a great "spacewalk effect". They supposedly have very little coma in fast Dobs, but cannot comment as I don't have a Dob. If you have a 2" diagonal the 2" skirt on the 9T1 saves the use of a 1.25 adapter but is oversized in a 1.25 diagonal. Can't comment on the speers-waller but many swear by them as much as I swear by the 9T1. (I have a pair for binoviewing)
