Depends on how it looks and runs. Cheap now is actually more or less wasted money if you just end up tossing it in the scrapbox later. A lightly used Botchmann or Aristocrap set from feebay isn't that much more.... and you don't have to buy a ton of batteries
The local Home Depot had this set a few weeks back for under forty bucks. It sold out in less than a week and has not been restocked. I was thinking of picking one up too...at the time, I thought it was New Bright (couldn't find any manufacturers marks on the boxes and I was pressed for time).
Thankfully, the Scientific Toys trains are vastly superior to the New Bright self-destructing trains. The main problem with the ST locomotive (as was noted in the review) is the derailing. This can best be remedied by sanding down the flange on the middle driver. I've done this to several of these locos and it completely got rid of the derailing. But you may want to add some weight to the engine as well; not a lot though.
I've also rebuilt three of the drives to track power for a couple of my projects. I was very impressed at how well they have lasted. I burned one out, but only after a long, long time pulling a decent consist. As Long as you don't run them too fast, the motors are quite durable.
The remote versions are particularly kid friendly and I owe Scientific Toys a big thank you for it. My younger daughter, (Dana the Great, as many of you know her)when she was five or so, was too intimidated by Daddy's trains to go near them. I set up one of these sets beside my tracks and gave her the control. She loved it and soon graduated to being one of the Rogue County Narrow Gauge RR's hardest workers. She's 16 now, I still have that train and it still works.
Let me 'splain MY opinion a little more. A coon's age ago, I bought this then brandy new Bachmann Big Hauler set, remember the original battery operated PoS?... After it crapped out (in about 2 months, and a zillion battery changes because it ate them like it was going out of style) I bought a 2nd Generation Pennsy Bug Mauler... which shed the wheel plating after about a week and constantly overheated.... For what I paid for both of those, ending with darn little to show for all the money spent, I could have bought an LGB starter set. Most of the LGB engines I now have (bought 2nd or 3rd hand) are 20+ years old and still going strong.
You pays your money, you takes your choices. too often I've found that the Wally-Wurld mentality of 'low price uber alles' ends up costing you more in the long run. If you want something to run for a little bit and throw away, or for little kids to destroy, this thing might just be perfect. Otherwise it kinda sounds 'penny wise, but pound foolish' to me.
My idea was to set it up to run around the tree to give the small kids that come over here (ages 4 and 2) something to watch (as well as something for the cats to bat around), then try to salvage something of the cars and whatnot after the holidaze. But since the sets are gone now, and money is getting pretty tight, it is a moot point.
