Scott, I can completely understand the costs involved in running your own business and supporting it. In my photography business the inventory costs alone would make many folks lose sleep, ex having to buy $20,000 worth of photo paper at a time in order to get a good deal on it. I think the prices are reasonable, but expect there are some things that could be done if production costs are the reason for needing higher prices.
I would be very surprised if the actual cost to produce any of these boards was much more than $20, and if so it may be worth taking the time to revise the components used to find less expensive, equal/better parts and/or ones that are expected to remain in production for years to come.
Something to consider as well, if there is any interest in producing any of the less in-demand boards. You could consider designing a more efficient panalization for production. It's likely that the boards will be produced on a panel that contains around 25-30 individual boards. It may be worth while to investigate designing the panel so that 1 or 2 of those boards are a less demanded product. In this way you can have a couple "free" ACC commanders for every 25 Cruise commanders that are produced.
I would appreciate a little guidance from the experts here as to exactly which ERR items I would need to order from 3rd Rail for upgrading the following engines...
...I will not be doing these installations-I'll leave that up to someone who knows what they're doing, but I would like to get the parts ordered for when that time comes. Help would be appreciated. Thanks
I might suggest speaking to whomever you are going to have do the installs. It is probably beneficial to all involved to have the tech order the parts. In this way first, they will know what is needed. Second, if you happen to choose an authorized ERR dealer, someone in the chain will save some money. It may be you pay less for the finished job, or it may be your tech makes a little extra, but in either case there is a savings to be had, and the tech knows exactly what part they are installing.
