Andekan recently posted some Starter Packs. There are US and UK plumbing packs, an IKEA product pack and a Victaulic pipe fitting pack for metric and one for imperial.
Now before you pass out when you see the price for a pack do some math. For example the US Plumbing pack sells for $3999.00 and there are 67 families that represent 702 models/types. This works out to about $59 per family.
Consider what you normally charge per hour (billable work) for your most knowledgeable Revit user. If your user can build one of these in just one hour how does that stack up? If it compares well, then let them try...if they give up...give Andekan a call. If the pack doesn't thrill you then you can look at an ala carte approach instead.
I first read about this at Alan's blog. Thanks for the post!
