Just go ahead and use your Elura 100 as the deck-
its a low end cam so why worry about it -(ebay $145)
By the time you ware it out there will be really cheap
memory stick cams available --new formats ect --
I used my Sony PD100 for 4 years as a deck---DVCam --
still works fine--
It works almost as good as my DSR 20 and better than a DSR 11
I had for awhile -
Also there can be problems with Cannon audio going out
of sink when using a deck -- some wacky audio sample rate --
we used to have problems with XL1 footage -dont know if its
resolved by now--Jay--
