I bought one few months ago. It is a good but slow machine.
You will have issues finding profiles for specific substrates and/or RIP's.
I bought mine in non-working condition and I was lucky that the local tech had two heads laying around and he gave them to me cheap, both for $300.
Got it up and running for around $600 paid to the tech. He was here for about 3 hours.
if you can get something better, go for it. If the Falcon is all you can afford or all you want to spend, go for it too. It is a good machine, but much slower and pretty soon, we'll have shortage of parts.
Another thing to look into, buy it now, and next year trade it in for a new one, you can get $4K off on the new machine. You can find used Falcon for 2K-3K and use it for a year for free and even make some money.
