You might consider looking for a Simson. They are the same guns as the Merkels and are usually about 1/2 the Merkel prices.
I blundered into this sweet Simson that is the same gun as the Merkel 8, which is the 47E without ejectors, has extractors. It was $600.00 and is in excellent condition.
If you need ejectors the cost goes up by $1K at least.
The 16ga is the top gun.
