Boxcar makes the Boxcar Base. Owosso Graphics just came out with a new version. There is also www.excelsiorpress.org , they just came out with a “chase base”, a different concept made out of hard wood that replace the entire chase. Occasionally, I have seen these on eBay and Craigslist.
Good Luck!
The best - Boxcar Press
The least expensive - occasionally on eBay
