There is no doubt that the preamps in the Juicedlink DT454 are good, and now that the Riggy RA333 has replaced it in the Juicedlink lineup, the used prices are starting to drop. Right now on ebay there is a Juicedlink DT454 with a starting price of $74. Not sure how high the price will go, but if it stays under $200 it’ll probably be a pretty good deal.
