Hi All,
        I want to back Anne's statement. I used to offer the largest
Supply of thin sections (which were FAR fewer than Anne offers
Now) and then "someone" (God bless him - he is a fine fellow -
Just that someone convinced him the work he was doing for
Him was as good as anyone's work) - flooded the TS market
with pure crapolla. These suckers were so horrid you could
see the inferior quality with the naked eye - but they were
CHEAP - less costly than the cost of the MATERIAL I was using,
Let alone the cost of an excellent TS maker (Anne uses the same
Expert I did - and David New did before us). Somehow a great
Many collectors thought if it looks "pretty" it is a good product,
So why pay 5 times as much elsewhere. So, I got out of TSs.
        A properly made TS is a diagnostic tool - so much so that
Many universities will only use those they make themselves.
Anne's are absolutely top notch - and I know they are very
Costly to have made to perfection. She also is selling E.T.s
Personal collection of 1,000 TSs - possibly the largest collection
In the world - so, if you want top notch quality, the largest
Selection in the world and at very reasonable prices, Anne is
where to go.
        Keep up the great work, Anne.
