He said they just got in 412 Smart Media cards.

I have ordered two spares.  When I purchased one in June they were $29.95 with free shipping.
Today they are $35 and still free shipping. 
The one that came with the Chelton did not work, even after formatting it.  The first replacement I bought cost over $50 so I decided to get spares as recommended on the lml list.

BTW, I have flown the necessary 25 hrs. and 9WG is going to the paint shop at the end of the month.
So far the airplane has performed beautifully.  Only problems so far is the SL30 had a recall on it, the GPS in the GADAHRS failed mid flight on 3 consecutive flights on 10/1/09.  Worked OK on the 7th. (4 short flights) and one short one on the 10th.  Oh, also a small oil leak which appears to be coming from the dipstick tube but not really sure.
