I have had a few Bedrocks go through my shop.
(NOTE the through... )
I have found them at various pawn shops, antique shops, junk stores and yard sales.
They do have a slightly different feel when in use. What I love about them is being able to find one cheap and then sell it to someone who wants the name.
So if you want the Bedrock mystique but not the price, look for some of the other planes with the same design. The Keen Kutter K series is a good example.
Another would be the early Bedrocks with the round sides. They do not draw a premium like the flat top Bedrocks.
When all is said and done, a good type 9 Stanley/Bailey plane is a fine user.
Sargent had a contender in this market. The Shaw's patent design adjusts the frog without changing the blade adjustment. I do not know how those go for price.
How often to people actually adjust their frogs?
For me, it is less expensive to have multiple #5 planes set up differently instead of having a single plane that always needs to be adjusted for the job at hand. Currently there are four #5 planes in my shop and the total cost was less than $45, some spare parts and fettling time.
