I think terrp extractors are having success right now, because of a good website and because of advertising here. Not because of good customer or new designs.
Everybody was on Redbeards nuts whenever he was advertising on here.
Is Wolfwurx that busy that they are not concerned with their website or advertising?
Allot of potential customers have never even heard of wolfwurx.
In this era, advertising/social media is everything for a startup businesses
Are they more geared at working with disp/mips than hobbyists/caregivers?
WolfWurx, Inc, is a small engineering consulting firm, whom contracts to project manage system design and building. Every machine is a custom build, with the machining, welding, and electronic controls contracted out, leaving only assembly and testing in house.
It is the assembly and testing that limits their production, and it has never been WolfWurx's intent to dominate the market, only to effectively service the contracts that they do accept and to be a dominant force advancing the state of the art.
The owner is currently more focused on both servicing existing contracts and learning the ropes himself, than a market assault, and already has a growing backlog, so don't expect to see significant volumes out in the immediate future.
Alas, their chief engineer is old and a decade past his professional retirement, plus warm, dry, and well fed, so motivating him to do much more than have fun solving mysteries and creating new stuff, is a project in itself.
Especially since he also services a few existing consulting contracts, and stays busy.
The market is awash with opportunities for successful equipment start ups, so room for everyone who puts out a sound competitively priced product, and services their customer's well enough for them to keep coming back.
What I find distressing and repugnant, are those start ups that appear geared to snatching the low hanging fruit supplying inferior and unsafe products, then bolting with the money, instead of developing a repeat customer base.
Second baddest, is would be suppliers who market their product by trashing the competition with untruths and partial truths, rather than lauding their own attributes that they deem superior.
Safe to say that most of the extractor suppliers are stretched as we speak, and you can't please everyone, especially those whom want everything immediately, if not sooner.
It is inevitable that everyone will come under attack sooner or later, so my suggestion is to look at the nature of those problems and what the supplier did about it.
While you may struggle to find accolades and kudos, lauding the product and service, you can more often find disgruntled customer's postings, giving insight into both the sort of problems they are having with the supplier, as well as how you might expect our own complaints to be handled.
There are simply a cheap sources of quality parts, cheap sources of even cheaper parts, and those companies that in addition to supplying parts, support their customers to insure they have a successful experience.
I would suggest picking the one that best suits your financial position and personal technical skills.
I am living proof that you can learn to run a Terpenator without instructions, so clearly not everyone needs the same level of hand holding.
Let your own situation be our guide.
