Welcome to the Village, Timelett. I've only been scrolling for about six months and started with a cheap WEN scroll saw. I'm already looking at purchasing a better saw. The WEN has a fixed upper arm that doesn't lift making it impossible to top feed and difficult to bottom feed. It does accept pinless blades but the clamping system is an issue. I've already had to replace the upper blade clamp and the screw knobs for both the upper and lower blade clamps have broken. I have my saw mounted onto a heavy stand I made and while the vibration is minimal, there is some that will strain your eyes over a period of time.
I've not personally had experience with the HF scroll saw, nor have I heard any reviews, but I believe you will get a taste of scrolling with almost any cheap saw. With that said, I have found scrolling to be very relaxing and enjoyable, despite the issues I've had with the WEN. My opinion is that if you find scrolling to be as enjoyable as I do, you will definitely be searching for a better quality saw in the near future.
Best of luck with your new saw and please share some of your work.
Happy scrolling!
