After the MD2020 I was seriously bitten by the rally bug and have added some accessories which I hope will improve my performance. This setup was done for less than $200 (and many hours of engineering trial and error). The RCI fuel cell was off of ebay, the backpack and fanny pack were thrift store buys, and the material for the dress up, and Lexan sheeting was from the Scrap Exchange in Durham. A lot of the miscellaneous expense was in fittings purchased and then not used (I hate plumbing).
