I've bought two chainrings for my 2005 Pista with a 130mm star from Sheldon Brown.
They work great and I like the price.
I know the Sugino and the Sugino/SR chainrings fit the Pista's Sugino RD crank perfectly.
TomD at Sheldon's can tell you which rings fit what.
I moved the ring to the outer position and flipped my EAI and Soma cogs so they had the flange inboard, and it gives me a perfrect chainline.
If you put the ring on the outer position, you'll need some shims for the retaining nuts.
The shims look like washers but they fit perfectly.
They come in two sizes.
Get the larger size.
