Marty, the reason its important to check some of the parts sites daily, is that sometimes only 1 or 2 of the very very last parts can be listed and gone very quickly.
**Example, no bugs bunny brand new playfields on any site for the last 2 years. Jumped on Marco's one morning , and bang, 1 x brand new NOS playfield placed up, and the last one ever. Their notification email system is weeks/months behind etc. If I hadnt of jumped on daily, well, you know the answer. NO Part. The 2 minutes of time was well worth it.etc
So, its not a waste of time checking parts sites sometimes daily "just in case", espescially if u score that elusive part..
Like the Lotto, got to be in it to win it.
