Welcome to the forum!
It's a sensible question as you want to ensure you get value and quality!!
The Custom brands on this forum are very good quality otherwise they wouldn't be on this forum for long as members who purchased would soon be vocal about bad points!
Lavers are decent bats - I have a number of newer ones and older ones (older ones = 3+ years old) and I personally prefer the slightly older profiles - but that is purely a personal opinion. You really don't get a great reputation like James Laver has without making superb bats! But I can fully understand the price implications at the moment - same as Screaming Cat!
As Joe mentioned Solitaire do seem to have a weight issue, but if you use 2'12+ then this shouldn't be a problem, as long as you make it clear that the weight you want the bat to be is fully dressed!
There are other excellent brands which are all worth considering such as H4L, Blueroom, Instinct, Charlie French, and Bulldog seems to come up with great deals too!
If I had to have just a single brand of bat though, I have always been honest and said that I would likely use Black Cat. The main reasons are that he has his own plantation of willow and can pick the absolute best - plus all the Black Cats I have had are absolutely superb!
There are other options on here too, such as the likes of Blank Bats and others who could offer an excellent service!
And some of my absolute best bats have come from Asad at Uzi Sports, so don't dismiss these other options.
I would take your time and see what takes your fancy!!
Sorry about too much info but there are no set answers as there really is so much quality from the sponsors on here!
It depends if you are looking to have something made whilst you watch, or want to order a certain profile, or simply want an stonker of a bat but not really too bothered about what stickers it has on it!
Just read lots and have fun deciding!
