Great bearings, great price!

I am rebuilding an old Delta/Rockwell drill press and was having trouble finding the correct replacement bearings at a reasonable price from my usual go-to online dealers; from those that even had them available. Shipping times where reasonable. Competitively priced at time of purchase. Stock status was available, had to use contact link to make sure they were available to ship. Would be very nice if real-time in-stock status could be available while hunting down need parts, but in the long run it's not that big of deal. The stock status email back following the inquire was quick with a quoted price and purchase link.
