Question 1: YES, so far there are 2 major equipment. average $10,000 USD
Question2: Just like BlackST said, you are looking at $500 and up!!! However, here in the US, DR Business is getting into some competition and prices are going down. $249 and up but $249 one usually cost additional $30 - $50 depend on how much data you want on the DVDs.
More and more places (proper equipment and SW) in the US are offering No Data = No Charge. I've seen No Data = No Charge DR companies to popup and disapear a lot but the good ones remain in the business. And a few of the No Data = No Charge DR Companies are working with local computer shops to take crashed drives from the home users for lower price range than the commercial customers. Average price I see is the DR companies charges $250 - $300 to the local computer shops where charges customers $300 - $500 on the physical data recovery. The business models I see is the local computer shop will charge customer the diagnostic fee from $50 and up and the diagnostic fee is the profit for the local computer repair shop. The DR company offer No Data = No Charge offer to the local computer shop, so the shop get profit by accepting the damaged drive and send it to the DR companies without suffering any loss, while DR companies save money from not creating a website or continue to post commercial ad on the paper and some DR companies are picking a cheap industrial park office, rather than an easy access retail locations to save operational costs.
A few I know, have moved from the industrial park offices to their own remodeled basement with a small clean room to further increase their profit with a cellular phone and free e-mail account to run the B2B style business.
Also, I see DR Pro guys are taking side jobs with reduced price, including myself...
Most of the DR companies who actually have the real tools should be able to help recover your data, but if you want the track records and reference, you might want to go with the big-name-brand DR companies who charges $1000 to start.
Other small DR companies in the US that can do the same job for about $299 - $499, but you are buying a peace-of-mind for added cost with the big name companies!!!
If you are going to use the cheap guys, just ask them what tools they use!!!! If they could give you the brand name tools, chances are you'll get your data back without paying $1000. One thing to remember is that DR is not a 100% exact recovery. There are failed recoveries due to some factors. This apply to small and big companies.
If you are looking to protect your data from others to see, you might want to ask your DR guy, if the company/he/she has a professional NDA form, instead of a short note stating they don't disclose your info. The real pro has a lawyer drafted NDAs on their premisses or even on the PDF.
I do hear good things about Harddrivespecialist, too. He does make a few funny comments here and there but he seems to be a confident DR Pro!!!
Seems like lots of AAKS are failing one way or the other.
