I spent $4,000.00 on a Cassese 299 to replace my Cassese 810 a couple of years ago. What a disaster, the 299 was broken down just about the entire time we had it. We had new parts on order after almost every use. We talked to Active Sales, Cassese main headquarters in France, Active sent a repair man down, all to no avail.
We ended up selling it back to the people we bought it from after a year for $1,000.00 less than we paid for it. All the Cassese 299 will do is waste your time and floor space. V mailers are not supposed to break down constantly, stay away from Cassese's new line-up, it is junk.
Keep your 810, Cassese actually did, at one time make one of the best V nailers you can get, the 810 is one of them. After all we went through, we are still using the twenty five year old 810.
If that is not an option, go with ANYTHING, except new model Cassese machines, you will not regret it.
