The dealer I buy my machines from gives free lessons for the lifetime of the machine as long as you own it. He does this for all machines bought from his shop. I've been dealing with him for 25 years and he still helps me with a machine I bought 25 years ago. I know I'm very lucky because other shops I've looked at don't offer this service (without a fee) and their personnel aren't as knowledgeable about all their products.
If you think you'll want/need personal attention I would check out your local independent dealers and find out what kind of service they offer, check with others that have bought from the shop and find out if they are happy with their service. Nothing is more frustrating than buying a machine and then being stuck reading a manual and trying to decipher it into "user" english, with no-one to call without paying for their help.
As others have stated, there's your further investment in threads, designs, etc. Some designs come on CD's and you need to have the software/hardware to put it onto a card to put into your machine. A blank card runs about $125. Plus, do you have a computer to make this transition? to the card reader that you have to buy. There are so many variables. If this is your first venture into an embroidery machine I would suggest you go to a local dealer if for information about all that is involved, even if you don't buy from them (but don't tell them that).
All this being said, when you get your embroidery machine you'll go nuts with all that you want to do and you will thoroughly enjoy it. It is good that you are asking questions and doing your research. You will go forward more informed and be able to ask questions.
It's a big investment so take your time. JMHO
