When I joined I received 100 free spins on Starburst rather than the 200 offered today, but they could also be played on Blood Suckers or Jack and the Beanstalk as well which are both much better games in my opinion. I'm unsure if that option is still available today however Next is a very fair casino in my experience and I believe the support would be willing to accomodate a new player if they wished to play a game other than the frankly terrible Starburst!
If I'm wrong though then definitely take a look at the alternative offer available here - you receive 125% rather than 150% of match bonus, plus 175 free spins on Steam Tower. The wagering requirement of 40x the bonus stays the same (30x on the winnings from the free spins) and the value more or less work out identically because Steam Tower has a higher number of lines and therefore higher betsize than Starburst.
The minimum deposit to receive the bonus is set at £25, which is a little higher than some casinos but still very reasonable. There is a maximum cashout of £100 shown in the terms and conditions on the portion of the freespins given before making a deposit, however I believe this is only enforced if you choose not to accept the welcome bonus portion of the offer - that said, considering I received just ten 10p spins on Starburst as my no deposit offer it would have been completely amazing had I been able to achieve a balance of over £100 from those spins alone!
Next offer two follow up bonuses we well of 50% and 75%, which seem to be common amounts in the industry at the moment. This makes the overall bonus package worth £700 in total, though I chose not to accept these extra bonuses on this occasion. If your anything like me you'll probably make a decision based on how well you do with the 40x wagering on this initial match bonus :)
