Expensive Seeds worth it?

I am currently looking at AK47 from serious and Jack Flash. I became intrested in these seeds from reading about their qualities. Would it be worth it to me to invest now and just get seeds from the after I grow?

If you're new to growing you may want to get some cheaper seeds until you get a better idea of what to do. But yeah, if you buy from a reputable seed bank generally the more expensive seeds are the higher quality stuff.
