You can still dispute past the 90 day period if you contact a manager at Paypal. I've had a dispute reversed over a year later after months of communication and evidence. Don't let him get away with this.
LLLL for $200 would be a good buy. Make sure it's either a chinese or english premium or semi premium.
Usually go for $350-500 though, you'd make some money if you manage it
Brandable LLLLL's are very good
That depends on if its a TLD etc. If I'm pricing an .au or .org domain, it usually prices it higher than it's worth simple due to the EMD keywords and search amount. I don't find it accurate at all.
Why would anyone think that Estibot is worth their clicks let alone a membership fee is beyond me.
Inaccurate and the only reason it should be used is to boost the price for an end user (Hey check out the evaluation here blah blah so expensive)
