Hi
Firstly, let me tell you that whichever machine you choose, it’s better than a lobster.
I’m not sure where you’re from, but I’ll assume the UK.
The biggest problem with lobster is that they don’t have internal ball direction. The top half of the machine rotates to do this. All siboasi machines have internal ball direction. Believe me, when you are playing in ‘player’/random mode - you don’t want to see where it is going to put the ball. this feature is invaluable.
also, lobsters are hugely overpriced.
as for siboasi, the s4015 is the top of all the ranges. Yes, you can program in a drill, but only one, and that is forgotten when you switch the machine off (I think).
it does have preset drills, both 2 line and 3 line (ie a 2 line will put a ball, say, deep far right, then short far left, a 3 line will put one on the right, one in the middle, then one on the left, then back to middle etc). You can also get it to do random base line drops, or vollies etc.
There is also single point anywhere, very effective top and back spin, speed and frequency control.
as for pricing - that’s a tough one. I used to import and sell them (uk only) but theygot very expensive and the (unavoidable) import duties were horrendous. Even at £2000 I’d barely make any money - so offering support or warranty just made it impossible to continue. Siboasi themselves were also difficult to deal with. Almost non-negotiable on price, inflexible and no real support. They also gave me no help or respect whatsoever in marketing or supporting their products.
The machines aren’t perfect either, even though they’ve had years to get them right.
there are some poorly designed features. The mechanics are somewhat fragile.
I’d still buy one though.
My advice - if you see a new one (s3015 or s4015) cheap on alibaba - see how much it costs to get it to your door (remembering you might get stung with import taxes). Or get a second hand one off ****.
hope that helps
