Seed compost

Does anyone know of a reliable seed compost? I swear the stuff has been getting worse year on year but I have just managed to buy what I consider to be the worst one I have ever had the misfortune to waste money on.....Levingtons seed and cutting compost. It's lumpy, compacted, fibrous, and impossible to break up. Dried out it might make good fuel but as a seed bed, it is abyssmal.

I've been using Grow Wise (Bord na Mona) with added JI for the past 4 years and pleased with the quality and results. It does contain peat. 3 x 50L /£12 around here.
They do produce a seed compost, but I can't find it locally.

I used seed compost once many years ago when I first started growing, vowed never to use it again, this year, because so many people said they used it and how good it was, I bought some, 2 different makes, never again, totally useless, so I will stick to my usual compost for seeds, cuttings and potting on.
and actually my first few seed trays I didn't bother sieving and the seeds still grew really well. I just changed method because a few of the seedlings had massive lumps of compost stuck to the top of the seed leaves.
But it was really cheap.
Clover multi purpose 100%
Thompson & Morgan Incredicompost 98%
Bathgate Champions Blend All Purpose 93%
Westland Jack’s Magic 90%
Levington’s was 5th with 82%, Bord na Mona got 53% (but was excellent for containers), and Wilko got 52%.
They also raved about a Panasonic microwave a couple of years ago when I needed to replace mine, but on the same page, all the comments from customers who owned this microwave were dire.
Which? isn't what is was... a bit like Levington's

as i understand it, for some seed types (typically smaller seeds/slower seeds...them you'd do in trays) it's important to use seed compost because its low-nutrient, it allows the roots to prosper whilst not putting on green growth above, thus leaving you with a good start for your seedling. you don't want tonnes of greenery and very few roots.
personally i buy any seed compost, sieve it, add about 20 to 30% vermiculite to help retain moisture.
