Hello -
If you eventually do decide for training, give yourself at least 16 hours on the system with the manual before setting foot in the classroom.
Remember that the VAR makes their living giving training, so it is profitable for them. Sometimes training can be used as a "deal sweetener". Maybe you can get some extra help at a slightly reduced price depending on how many seats you will potentially buy and how hungry the seller is to get the sale of the seats and yearly maintenence contract.
While you can learn lots from a qualified trainer, you can learn just as much from "time at task", and possbily even more. If you and your people are quick studies in CAD you can learn a lot on your own, but geting help from someone who knows is also great.
If you eventually do go with solidworks, you get (at last glance) a nice printed manual and a tutorial book which are really great for you when you are starting out. Another alternative - do you know anyone who could help you for a lower price or simply be your CAD mentor? Training can come from anyone, not just your reseller (but be careful in who you choose - you know this).
Also, you might want to consider joining using your local solidworks user group as a way to get some tips and peer-to-peer training. Usually these groups are full of knowledgeable people willing to share their ideas and experience. Naturally karma would dictate that you return the favor once you become proficient.
Best Wishes-
